Parsing of "distributed systems online" paper does not work

Follow-up to https://github.com/JabRef/jabref/pull/12018

PDF from https://www.computer.org/csdl/magazine/ds/2002/02/o2001/13rRUEgs2Q8

Attention! The PDF must not checked in to JabRef while fixing. One can use it for local development though.

The tests could be written in a way that they are executed if the file exists ( assumeTrue) - and skip if it does not exist. Then the JAvaDoc says where to download the PDF and where to place.

@leaf-soba Can you have a look?
